IE 5.5 sp2

Go to www.windowsupdate.microsoft.com

IE 5.5 SP2 is the lastest update for that version,the next update was the release of IE6,which has security patchecs updates that can be downloaded from Windows Updates.

The anti-virus update is not updated with IE,this would depend on the anti-virus software installed oon the system,checking manufacturer to check the web to see what updatte has been released for the current anti-virus software

i know I.E. 5.5 sp2 is totaly different from virus software. I also know that the windows, update site has the newest version for most microsft products. My question in a clearer sense was due to the number of security holes in I.E 5.5 that has leftif more prone to virus attacts. I have an up to date virus scanner and it picks up the viruses, i just need to know the list of new fixes released for IE.5.5 and i only found some info at the technet site. I.E.5.5 has new hotfixes but i need to document them and provide facts..
